Frequently Asked Questions
Everything you need to know about steel plant electronics repair with Synchronics.
We repair all major rolling mill drives — ABB ACS880 and ACS6000 medium-voltage drives, Siemens SINAMICS S120 and GM150 medium-voltage drives, GE DC2100 digital DC drives, and Allen-Bradley PowerFlex 7000 MV drives. Our scope covers everything from main stand drives and roughing mill drives to looper drives, coiler drives, and tension reel drives across hot strip, cold rolling, plate, and section mills.
Yes. We maintain component stock for legacy Siemens SIMADYN D control boards and SIMOREG DC master drives that are still widely used in Indian rolling mills. These boards contain custom ASICs and obsolete components that we have sourced and inventoried specifically for steel plant customers who cannot upgrade to SINAMICS immediately.
Yes. We repair electrode regulation controller boards from ABB, Siemens, and Danieli — including thyristor firing cards, current transformer interface boards, electrode position controller modules, and power factor correction controller cards. Our repairs restore precise electrode regulation for stable arc operation and consistent melt quality.
48-72 hours for most drive control boards, CU320 control units, and regulator cards. IGBT power modules and medium-voltage power cells may need 5-7 days if custom sourcing of specific power semiconductor devices is required. We maintain stock of the most commonly failing IGBTs and thyristors for major steel plant drive platforms to minimise turnaround.
Yes. We repair mould oscillation servo drives from Bosch Rexroth IndraDrive, Siemens SINAMICS S120, and ABB ACSM1 platforms — including servo amplifier modules, encoder interface cards, and hydraulic valve amplifier boards used in hydraulic mould oscillation systems. Precise servo performance is critical for slab surface quality.
Yes. We repair hoist, travel, and cross-travel VFDs for EOT cranes from ABB, Siemens, Danfoss, and Yaskawa — including brake chopper modules, contactor interface boards, and encoder feedback cards. Steel plant crane drives operate in extreme heat and dust conditions, and we address both the immediate failure and environmental degradation during repair.
We serve all major steel manufacturing cities and clusters across India — Jamshedpur, Rourkela, Bhilai, Visakhapatnam (Vizag), Salem, Bellary (Ballari), Mumbai, Pune, Ahmedabad, Raigarh, Dolvi, and Hazira. Pan-India courier pickup and express return are included with every repair. Emergency same-day dispatch available for critical production situations.
Yes. GE DC2100 and DC2000 digital DC drives are within our core repair scope — including SCR power boards, main regulator cards, firing cards, field excitation modules, and communication interface boards. These drives are widely used in Steckel mills and plate mills across India, and we maintain component inventory for fast turnaround.
